我正在遵循与Apache Apex相关的文档，该文档有助于创建启动项目。https://apex.apache.org/docs/apex-3.4/apex_development_setup/#creating-new-apex-project
执行Maven命令时，
@echo off
@rem Script for creating a new application
setlocal
mvn archetype:generate -DarchetypeGroupId=org.apache.apex -DarchetypeArtifactId=apex-app-archetype -DarchetypeVersion=3.5.0 -DgroupId=com.example -Dpackage=com.example.myapexapp -DartifactId=myapexapp -Dversion=1.0-SNAPSHOT
endlocal
我面临以下问题。

此错误的原因是什么？
您与Maven存储库的连接可能存在问题。尝试手动下载必要的工件：
mvn dependency:get -DremoteRepositories=http://repo1.maven.org/maven2/ -DgroupId=org.apache.apex -DartifactId=apex-app-archetype -Dversion=3.5.0
